babylon-gltf-rigid-body-loader v0.2.1

About

An importer for loading glTF files with rigid body information into Babylon.js.

For more information on how to specify rigid body information in your glTF files, see the KHR_rigid_bodies repository. This package supports two extensions for being able to specify rigid bodies - the KHR_rigid_bodies extension is under active development and, as such, may experience name changes which requires assets to be re-exported. If you want a more stable experience, the MSFT_rigid_bodies plugin has a frozen feature set, and won't be experiencing any breaking changes. Both plugins can be used simultaneously or independently.

If you're using Blender, you can add the Blender glTF physics exporter addon to export physics information with your existing Blender files. Use the hk_users branch if you wish to export using the MSFT_rigid_bodies extension.

Usage

Install the package:

npm install babylon-gltf-rigid-body-loader

In your project, register the extension with Babylon's glTF loader:

import { GLTF2 } from "@babylonjs/loaders";

// Latest, development plugin; might change in the future, which might break assets!
import { KHR_RigidBodies_Plugin } from "babylon-gltf-rigid-body-loader";

GLTF2.GLTFLoader.RegisterExtension(
   "KHR_rigid_bodies", function (loader) {
       return new KHR_RigidBodies_Plugin(loader);
   });


// Stable, feature-frozen plugin; won't make any breaking changes to assets:
import { MSFT_RigidBodies_Plugin } from "babylon-gltf-rigid-body-loader";

GLTF2.GLTFLoader.RegisterExtension(
   "MSFT_rigid_bodies", function (loader) {
       return new MSFT_RigidBodies_Plugin(loader);
   });

Ensure that you've called scene.enablePhysics() on your scene before loading any assets containing physics information.

Load your glTF assets as normal!

Demo

You can try out a live demo with samples served from the specification repository - other files can also be dragged-and-dropped into the window to load them, for easy testing.
